Phaser 7800 - Cyan Toner Not Recognized

Product Name: phaser 7800dx
Operating System: macOS 10.13 - High Sierra

Hello! I just tried installing a new cyan toner cartridge (official xerox brand bought on amazon). I verified model# o of the supply as being correct (106R01566) on both the box and the toner cartridge itself. I've tried restarting a few times, and nothing, it's just not recognizing it. I also checked the imaging unit for the cyan path is at 75% still usable.

Any help would be greatly appreciated!

Hi - thanks for the suggestion! I updated to the latest firmware and unfortunately, it's still not being recognized. Tried taking out and reinstalling and restarting the printer fully and still nothing. Looks like next step will have to be a tech come out to have a look. Thanks though!
